Abstract
The invention relates to an ecological recovery method for vegetative cover at the mine spoil area in southern China, and the technical proposal thereof is as follows: first, the mine waste residue substrate is stationed and dug with pits, each pit is not less than 50cm *50cm*50cm, the pit is filled with soil for planting inside, the soil for planting is loess or other soil, then nursing plants, namely, one to two large leaf acacias are planted, after the large leaf acacias survive for 3 to 5 months, indigenousspecies lotus tree, psychotria, huajillo, or red clover are planted under the large leaf acacias to be used as the objective plant species. After the nursing system and the nursing plants-the objective plant species pair are established, the curing is only needed for twice to three times in early time, and finally the indigenousspecies all can be directly settled on the mine spoil area.
Description
Technical field
The vegetation ecological that the present invention relates to exposed area recovers, and particularly relates to the vegetation ecological recovering technology of mine waste residue field, South China.
Background technology
The child care plant is meant the species that can utilize auxiliary other target species of its hat width of cloth to grow.The child care plant mainly provides microenvironment preferably by seed germination or growth of seedling to target species, and by the positive-effect between plant species the target plant kind is successfully settled down.International in recent years ecology recovering educational circles has begun to be applied to the child care plant technology in the revegetation and to have obtained some effects.The child care plant plays key effect in recovering primary ecosystem features and function, also be considered to that succession is had driving action in some habitats (especially disturbing the habitat).The success or failure of the selection of child care plant decision ecological recovery, the main biome research and determined some child care and target plant in the world in recent years.In extreme habitat, best child care plant is the autochthon that favourable microhabitat can be provided for seedling establishment.Although some denizens are used as the child care plant and successfully use, also to prevent the danger of biotic intrusion.The child care plant of discovering the shape of growing thickly has tangible child care effect in less time of rainfall to the survival of seedling.Leguminous plant is sheltered from heat or light effect and has potentiality of " child care plant " because can improve the Soil Nitrogen condition and have, leguminous plant can significantly improve the survival rate and the growth rate of target plant in the semiarid habitat in desert and Mediterranean, but child care plant and target plant when being the pulse family kind effect bad.In the desert, shrub tends to serve as the child care plant of other plant (particularly Indian fig) seedling.In forest, seedling can successfully be settled down around the plant that grows up usually, because the plant that grows up can be improved some extreme ecological factors.The species characteristic is depended in interaction between the plant, therefore the selection (i.e. the species that will recover) of target plant also can influence the effect of recovery, and the ecological demand of target species self and the ability of handling uncomfortable habitat thereof determine the balance of this correlation.The child care effect realizes by the middle factor (as soil) that influences the species intercropping and use, and the child care plant mainly exerts an influence to seed and the seedling stage of target plant history of life, and wherein the seedling stage more likely shows the child care effect.The child care effect increases along with the abominable of abiotic condition, and the child care effect of child care plant is stronger in the higher habitat of height above sea level, and it is more obvious than deuterogenesis's child care effect to recover commitment at degraded ecosystem.
Summary of the invention
The objective of the invention is to propose a kind of method of carrying out the vegetation ecological recovery by the plant conservation effect in mine waste residue field, South China.
We find, in the South China, by selecting good child care plant for use, utilize plant species to the child care effect, can well solve indigenous tree species or the target species problem of settling down on the mine waste residue field of extremely degenerating, reach the revegetation target, thereby realize purpose of the present invention.
Technical scheme of the present invention is as follows: at first layout on mine waste residue matrix and dig pit, each hole, hole should be not less than 50cm * 50cm * 50cm, in the hole, insert and plant soil, the described soil of planting can be loess or other types soil, plant child care plant acacia auriculiformis (Acacia auriculaeformis) one to two strain then, after acacia auriculiformis survives 3-5 month, plant autochthon lotus wood (Schima superba) down at it, nine joints (Psychotria rubra), pithecellobium clypearia (Pithecellobium clypearia) or screw oil expeller (Syzygium hancei) are as the target plant kind.Child care system and child care plant-target plant kind only need maintenance in early days twice or thrice to after setting up, and finally these autochthons all can directly be settled down on the mine waste residue field.
The present invention is good to revegetation success rate height, the effect of extreme degraded lands such as mine waste residue field, be convenient to operation, be easy to apply, thereby a kind of easy and simple to handle, with low cost, obvious results technology for recovering vegetation that this class extreme degraded land of mine waste residue field is carried out revegetation is provided, had the great application prospect and the market demand.Applying for effective ecological ragime, raising land reclamation effect of improving the extreme degraded land of it has important effect.
Embodiment
Below the present invention is further illustrated with the effect that carries out revegetation in extreme degraded soil terrestrial applications the technology of the present invention of slag heap, but the invention is not restricted to following embodiment.
Embodiment one
The revegetation implementation process of maoming oil shale spoil area:
The maoming oil shale spoil area does not almost have soil, majority has only the discarded oil refining not of uniform size rock slag that gives up, water conservation is not protected fertilizer, there is not magaphanerophytes's necessary primary condition of growing, indigenous tree species can't be settled down at all and be survived, go through the two more than ten years several shrub herbaceous plant few in number that still only growing, almost the still nude ground of a slice.Carry out revegetation by the inventive method, dig pit (interval of respectively cheating between the hole is as the criterion to have the enough spaces that are suitable for the plant propagation growth) of layouting on the spoil area, the size in each hole, hole all is not less than 50cm * 50cm * 50cm, in the hole, insert loess, the plant of plantation child care earlier acacia auriculiformis one to two strain in the hole, hole that each bankets then, plant target plant kind autochthon lotus wood after surviving again respectively, nine joints, pithecellobium clypearia or screw oil expeller, formation comprises acacia auriculiformis-autochthon lotus wood, acacia auriculiformis-autochthon nine joints, acacia auriculiformis-autochthon pithecellobium clypearia, child care plant-target plant the kind of acacia auriculiformis-autochthon screw oil expeller etc. is right, through the time in about 5 years, " flame hill " looks are originally greatly taken on a new look, not only taller and bigger child care plant growing is dense, and also well-grown of target plant, and many kinds of one's native land such as Radix Wikstroemae have been arranged under the child care plant, hang upside down pen and wait settling down of indigenous plant, vegetation initial success recovers.
Claims (2)
1. the vegetation ecological recovering method of mine waste residue field, a South China is characterized in that:
On the matrix of mine waste residue field, layout and dig pit, each hole is not less than 50cm * 50cm * 50cm, in the hole, insert and plant soil, plant one to two strain of child care plant acacia auriculiformis then, after acacia auriculiformis survives 3-5 month, plant the target plant kind down at it, described target plant kind is autochthon lotus wood, nine joints, pithecellobium clypearia or screw oil expeller.
2. the vegetation ecological recovering method of mine waste residue field, South China according to claim 1 is characterized in that the described soil of planting is loess.
